 Posted: Sun Aug 10, 2003 8:06 am Post subject: GRUB - Cannot start linux |
 |
|
I have finished the installation but i can't get GRUB to work.
My hard drive configuration is as follows:
hda1 - WinXP
hda5 - FAT32
hda6 - FAT32
hdb1 - /boot (Ext2)
hdb2 - Swap
hdb3 - / (ReiserFS)
I set up grub according to the instructions like so:
| Code: |
grub> root (hd1,0) //ie hdb1
grub> setup (hd1,0)
grub> quit
|
My grub.conf
| Code: |
default 0
timeout 10
splashimage=(hd1,0)/boot/grub/splash.xpm.gz
#Linux
title=Gentoo
root (hd1,0)
kernel (hd1,0)/boot/kernel-2.4.20-pfeifer-r1_pre11 root=/dev/hdb3
initrd (hd1,0)/boot/initrd-2.4.20-pfeifer-r1_pre11
|
When I change the BIOS settings to try to boot from the second drive
into linux all is this error.
| Code: |
root (hd1,0)
Filesystem type is FAT, partition type 0xc
kernel (hd1,0)/boot/kernel-2.4.20-pfeifer-r1_pre11 root=/dev/hdb3
Error 15: File not found
Press any key to continue...

Any help would be great. |

you should not have to go into the BIOS to boot linux... you should add lines to grub that point to windows. Then you will have dual boot with grub.
Setup Grub onto the MBR (hd0) and base your grub.conf off this dual booting example.
| Code: | default 0
timeout 30
splashimage=(hd0,0)/boot/grub/splash.xpm.gz
# If you compiled your own kernel, use something like this:
title=My example Gentoo Linux
root (hd0,0)
kernel (hd0,0)/boot/bzImage root=/dev/hda3
# If you're using genkernel, use something like this instead:
title=My example Gentoo Linux (genkernel)
root (hd0,0)
kernel (hd0,0)/boot/kernel-KV root=/dev/hda3
initrd (hd0,0)/boot/initrd-KV
# Below needed only for people who dual-boot
title=Windows XP
root (hd0,5)
chainloader (hd0,5)+1

Hope that helps. |

| Thanx, i think i'll just add GRUB to the MBR like the post described. |

This is the 4th one that I've seen do this incorrectly. Are there some old install doc's someplace that are causing this? I'm at this same stage too and have 2 separate HDD's. The doc's that I'm looking at say:
| Code: |
grub> root (hd1,0) //ie hdb1 where the boot partition is
grub> setup (hd0) //* Note NOT (hd1,0) // installs to the MBR
grub> quit
|
In particular 23.2 and 23.3 of the x86 install doc's. Seems like there enough people with 2 HDD's these days (since they are dirt cheap) to update the doc's with more specific directions on dual-booting Windows XP on hda and linux (Gentoo) on hdb.
I've been trying to figure out if I can install grub elsewhere on my linux partition and not on the MBR. The idea that I thought might work is to change the boot order in my BIOS setup to start with hdb and/or to use the makeactive command in my grub.conf so that grub can reside on the linux partition and dual boot Window XP rather than loading grub on the MBR and crossing my fingers that Window still loads.
See the thread HERE. I'll post when I get a chance to test some of this out. |

I remember seeing that in the docs; they are correct for people who want to chainload to GRUB using a third party bootloader (PowerQuest BootMagic, etc.). There's another snippet in the docs (quoted somewhere above) for people who need to use GRUB as their sole bootloader.
So, to sum up for any lurkers:
In GRUB, if you have two hard drives and want to use GRUB to boot to all your OSes, type:
| Code: |
grub> root (hd1,0) # use '0' if your /boot partition is /dev/hdb1
# if it's, for example, /dev/hdb3 use (hd1,2)
grub> setup (hd0)
|
Whereas if you have two hard drives and want to use a third-party bootloader to get to GRUB and boot Linux:
| Code: |
grub> root (hd1,0) # See above about that 0
grub> setup (hd1,0)
|
caveat: the bootloader that comes with Windows will *not* chainload to GRUB or LILO; you need to use a third party bootloader like BootMagic or System Commander.

| Posted: Mon Jan 03, 2005 7:29 am Post subject: more questions about using BootMagic, with or without GRUB |
|
|
I'm new to the world of Linux and of booting a selection of OS's in general.
In the above post, and in a couple of other posts on the subject that I found by searching, they all suggest that when using BootMagic, it should boot GRUB which is located on a 2nd hard drive, and then GRUB should in turn boot Gentoo Linux.
But I have only one physical hard drive, with multiple partitions. I started within Windows and used Partition Magic to create all my partitions and then installed BootMagic. Then I used a Gentoo LiveCD to install Gentoo onto one of the partitions (but I skipped the installation steps that had to do with GRUB). Now I want BootMagic to dual boot to Windows or Gentoo Linux.
The Gentoo installation handbook seems to assume I am using GRUB or LILO (or some similar Linux bootloader). Do I still need something like GRUB if I have BootMagic? If I setup GRUB on a different partition, but the same physical hard drive, as BootMagic, will the two conflict in trying to take over the mbr? I tried not using GRUB at all but just setting BootMagic to point to the partition where Gentoo is installed, but it just hangs when I try to boot into it.
Can someone give this Linux newbie an education in how to do this? |
